  • selfhost.eu offers dynamic DNS which works perfectly fine with my router, using their API access as documented by them. It also works perfectly well with Let’s Encrypt integrated in Nginx Proxy Manager.

    • can handle .at domains
    • is not Cloudflare
    • is registrar and name server
    • is European (Germany)
    • supports Nginx Proxy Manager

    They’re in the market since 2001, I use them since ca. 2010 and never had any issues. Their website looks ancient, almost historic. But it’s functional.

















  • Security … Depends. If you want to sell the SSD, then yes, wiping the SSD is advised. You don’t need complicated random multiple-write patterns. Just make sure to wipe everything (keywords: wear-leveling, cache), you could use blkdiscard for that.

    Performance-wise nothing noticeable would change. Physically, SSDs are fast enough to modify the charge traps to store the bits as needed to store files regardless of what’s in those traps (that’s quite a rabbit hole).

    If you plan using the SSD for your own, you don’t need to wipe it, just repartition as needed and create the file systems in the partitions. What I do, is writing some data to the storage to destroy the partition table (dd if=/dev/urandom of=/dev/XYZ where XYZ is my target device – and then leave it runninf for a few seconds).

    Since you’re using encryption, the common tools only see garbage and no data (i.e. file system). So simply don’t decrypt and work with the mapped partition but use the device directly.
